我国许多煤矿区,由于地下水频繁突入,造成淹井或因突水威胁使大量煤炭资源难以开发。因此,准确预测矿井涌水量,为矿井防治水提供依据,对煤矿床安全开采和长远发展至关重要。以宁东煤炭基地麦垛山煤矿为例,采用解析法、水文地质比拟法和三维渗流数值法等六种预测方法,对该煤矿11采区110203、110208工作面2#煤顶板直罗组底部砂岩含水层进行了涌水量预测。通过各种方法的分析比较,最后推荐采用最小二乘比拟法预算结果做最终矿井涌水量。

In many Chinese coal mining areas, plentiful coal resources are difficult to exploit because of frequent groundwater inrush causing coalmine flooding even water bursting. Thus, exact mine inflow growth prediction can provide basis for mine water controlling, it ’s essential to mining safety and long-term coal exploitation. Taking the Maiduoshan coalmine in Ningdong coal base as example, using 6 prediction methods including analytical, hydrogeological simulation, 3D seepage numerical methods etc. predicted water inflow from the coal No.2 roof Zhiluo Formation bottom sandstone aquifer into coal faces in winning district No.11 of the coalmine. Through analysis and comparison of results from various methods, finally, the result from the least square simulation method has been accepted.
